The BB 16500 was the first locomotive from the “BB Alstom” family. Despite its output of only 2,580 kW, it was built in large numbers in order to get enough locomotives for the new 25.000 Volt power system. Like many of its successors, it had bogies with only one traction motor each and a two-speed gearbox for freight and passenger trains. With these, a top speed of 100 or 140 km/h is achieved with different tractive efforts. They were retired between 2002 and 2011.

The BB 20200 was a member of the “BB Alsthom” family that was intended for mixed traffic across the borders with Germany and Switzerland. They were created by taking 13 BB 25500 from the production line and adding the equipment needed for operation under 15 kV and 16⅔ Hz. The basic locomotives were already capable of operation under 25 kV 50 Hz and under 1.5 kV DC. This also meant that these locomotives had monomotor bogies which could be switched between a top speed of 90 and 140 km/h while stationary. All locomotives were equipped for push-pull operations and double-heading. As their short bogie wheelbase led to bad running characteristics at speed, they were almost always used in freight service and rarely in passenger service. Another downside was that they only delivered 1,660 kW on 15 kV, compared to 2,940 kW at 25 kV. The last ones were retired in 2006 and BB 20210 is being preserved in the “Cité du Train” at Mulhouse.

BB 25150 designates a total of 45 four-axle electric locomotives built in three batches between 1967 and 1977. They were equipped for both systems used in France, 25 kV AC and 1.5 kV DC. While they delivered 4,130 kW when running under AC, they only made 3,400 kW under DC due to the lower voltage. Like the earlier BB 25100, they had a top speed of 130 km/h, as opposed to the 160 km/h of the BB 25200. In 2003, four were actually rebuilt to BB 25200, while the withdrawals of the remaining locomotives started in the same year. After withdrawals had been completed in 2011, only BB 25188 is being preserved and operational.
